A Google employee announced that the official Android 5.0 Lollipop will be available soon for Nexus 4 owners so they can join the rest of the nexus family who are already running the OTA updates. Even without the OTA rolling to notification panels for device owners, we can still update the nexus 4 to the LRX21T build using the official factory image. The folks out of the Googleplex made the images available. Therefore, whether you updated manually using the factory image, or if you are reading this at a later date and you installed the official over the air update, you can use this guide to gain root access on the new Lollipop software.
As usual, there’s a list of essentials you must read before getting to business. The first thing you want to note is backing up. We must backup the EFS folder before applying root access and unlocking the system internals. If this folder is corrupt it can cause issues without another copy. Next you want to search the Google Play store for a number of applications that will help you in backing up everything on your phone. We recommend using Helium for Android for backing up the market applications and syncing the phone contacts. Furthermore, SMS Backup+ is a great way to store the text messages from your friends and family that you don’t want to risk losing. Additionally, you can check out others such as G cloud backup for those preferring to store data in the cloud, Holo Backup and more.
You must have the LG Nexus 4 USB Drivers. Moreover, stopover at the Settings > Developer options and enable the USB Debugging mode. Now you are all set to connect the phone to the computer successfully. The last thing you need is the USB cable that comes out of the box. Most people use the same wire for the phone charging cable. Therefore, if you have trouble locating yours, try looking at the phone charger wire.
The following steps are compatible for users who own a Windows computer, Linux computer and mac computer. It doesn’t matter the brand from open source, to Microsoft and Apple. However, the steps slightly differ for each. Most notably is when you must type a different command and download a different file. We run through the steps for each operating system during the guide clearly, so there’s no reason to worry.
The Nexus 4 comes with USB charging as a default feature. That means the phone starts charging instinctively all by itself once plugged into the computer. It works by taking some of the power coming from the computer. The computer must be working for that to work. That’s not a problem since we must have the computer on for doing our work at the same time. Nevertheless, not all phones have the USB charging feature working. If yours is not working you should reserve enough battery to see through the guide without the phone turning off beforehand. If the device doesn’t make it to the end it can result in soft-bricking of the handset. Now you will require a different guide to fix the problem. Therefore, it’s a great idea to have at least 50% battery saved up before starting. You can check the battery level by observing the battery icon from the status bar.
The following guide is for experienced Android users. You must have experience with Android SDK. It’s a unique method that’s popular for the Nexus range.
Android 5.0 for the Nexus 5 comes with loads of features including lock screen notifications, Material Design UI, Recent multi-tasking, multi-user support, Android Runtime, OpenGL ES 3.1, Google Now enhancements to the “OK Google” menu, priority call features and more. A few lesser known features include improved camera software, dynamic status bar, battery saving mode and print preview.
The following steps will apply root access along with clockworkMod recovery. TWRP recovery does work. The choice is yours! However, you must flash at least one version of recovery or else there’s no unchaining of the operating system.
Once you open up the internal hardware away from the default factory restrictions you can start exploring with custom ROMS and applications that are not available from the Google Play Store. Some of our favorite apps include Children tracker, BBQ Screen, FPS Meter, Experience pro, Icon Themer, Softkeyz, Nandroid manager and more.
